When I found a set of D 1 s I ended up buying a set of lug nuts and machining them to fit. I think I only had to shorten the shank. While working on a Choke I was not happy with the metric lug nuts and stud they come with. After ordering several sets of metric lugs none of which I was happy with I started visiting general machine shops for custom built lug nits. Working with stainless hex stock low bid was just under $1000 for 20 lugs nuts, a few spares seemed like a good idea. That was not working for me so I changed the front drive flanges and rear hubs to std 3/8 fine studs and machined some lugs that were close. You may want to check a 6 point thin wall socket. I had my 38 mm verto flywheel bolt socket machined to clear the locking flange washer made on to the bolt. Steve (CTR)

It sure is a very attractive and unique wheel!  I think the one in John's post above might be for the Honda.... you can see the lug stud hole looks a bit more outboard in the wheel that the one in the original post.... wasn't the Honda 4 on 100mm? That would give a bit more room for the socket.

I couldn't find any catalogs from the San Jose days,  although I bet Don might have some!  I wonder if the custom lug nuts it required were available or if they were supplied with the wheels.   How thick is the flange or wheel casting where the lug stud holes are?  Shouldn't be difficult to bore the holes to 9/16", then you'd could just use some washers to space the stainless steel revolution nuts out to clear the spokes.... These could easily be cut down in length:

The Pos-A-Traction alloys were offered for both the Mini and the Honda N/Z600 range. They were more common on the Honda's (at least here in SoCal). Finding the correct lug nuts has always been a challenge with these great looking wheels.

Here is a link to a photo of a restored Pos-A-Traction (not sure if Mini or Honda). Anyhow it highlights just how tight the clearance is for the lug nuts and how sharp these wheels can look when cleaned up.



I'd recommend hitting up some of the local CNC shops to see what it would cost to make some (or maybe an online CNC outfit).

I know Heritage Garage in Costa Mesa was working on a project that required these wheels about a year back. They may have some lug nuts in stock or a source. Worth a call or email to find out.

Jemal, If MM has an archive of old catalogs from the early days you might find these were a stocked item at one time. I think I have an old Mini City catalog listing them.

Another thing to consider.... can you center the wheel on the hubs with a close fitting collar such that you CAN just use standard nuts and flat washers to CLAMP the wheel, rather than having to 'center' the wheel on the hub as most lug nuts try to?  It seems to me that wheel was not intended for the Mini, but rather just happens to have the not too uncommon 4 x 4 inch pattern. So do lots of little trailer wheels from harbor Freight!  Quality grade 8 nuts in 3/8-24 thread generally take a 9/16 socket, so might be workable!

Thank you for the reply.

You are correct.  There is very limited space.  I stopped at the club, shop yesterday to see what socket fits the lug nut.  A 5/8 socket just fits between the "spokes".  I don't think the next size socket 11/16" would fit.  Maybe a thin wall socket would fit, if they are even available.

As for the shank wall thickness; remember the shank is in the wheel, captured and not going to break out, I hope.  Still I agree, thin wall no doubt.

So now I need to look for a 5/8" hex lug nut, with a straight shank.  Then I have a choice.  Machine the wheels or machine the shank to the diameter and length I need.  Either way, kind of stinks.  If I machine the lug nut, the chrome will be machined off.  If I machine the wheels, I will have to remove the tires etc etc. what a pain.

Who would make a what I think is a cool wheel and not have standard lug nuts?  They must NOT be standard as I can find no other mfg of this size.  Not even close.  And I have been looking.  I thought Honda 600 was going to be the one but no way.

What you're up against is the limited physical space available!  3/8 -24 thread inside a "tube" with an OD of .5 inches leaves a max. wall thickness of .0625 not counting cutting thread and reasonable clearance to actually fit the wheel over the studs and the lugs into the wheel!  The closest standard 'available' nut will indeed be the "mamba" or "Revolution" wheel style which are supplied with an OD of 9/16" or the aforementioned .562.

Just about all "standard-ish" Mini lug nuts have an 11/16" hex head.  Sounds to me you'll absolutely have to custom make some lug nuts, or modify the wheels!   You may get away with machining a tiny chamfer to create a 60 degree "V" so that typical modern-design lug nuts like these will work:

These still have 11/16" hex heads as do just about all the available Mini lug nuts.... If you can't get around that clearance, you may have to consider another approach.... perhaps some custom made counter-sunk Allen bolts instead of studs and nuts? Perhaps modify your hubs up to 7/16 or even 1/2 inch thread! 

The lug nuts used on a Triumph Spitfire, may work for you, BUT will need a little modification. You would need to reduce the OD and the length.  The thread size is 3/8 fine thread. The shank has a groove to hold the plastic washer in place. The plastic washer is used to hold the hub cap in place.

Hello.

Thanks for the info.  Much appreciated.  I attached a recent picture.

I very much like the wheels.  The car came with them when I bought the car.  They were filthy.  I had no idea they would clean up this nice.  Also, two of the wheels had 3 lug nuts holding the wheel on.  One wheel had only two lug nuts on and a standard "bolt" nut for a total of 3 nuts holding the wheel.

This is why I need a few lug nuts.  If I could find a standard lug nut, I would make all 16 lug nuts the same, new, pretty, chrome.  I have been getting by with Lug nuts from my Lotus.  Same size but just steel std lug nuts.

Regards
Tim

 That's a handsome wheel Tim. They remind me of Halibrands used on the early Cobras and GT40s. I like the dull mat finish. Good luck on finding lugs to fit. Show us what they look like when you get them mounted. 

i've been looking for Anodized wheel lug nuts for classic minis, blue or red.... can't find one...

I would ask the question on TMF in the UK more likely someone has a set of the wheels and knows of a supply of them.
Alternatively 7/16 stainless bar stock isn't expensive you could start a cottage industry making lug nuts.....

Try contacting Quicksilver on here. I believe he had a set of these wheels he had on his car. Inquire about his lugnuts.

Willie_B +1 I have looked forever for the Mfg of those wheels. I did a search for Pos-A-Traction and found some. Unbelievable. Thank you.

JEFF10049 Thanks for the reply. I understand I can modify existing lug nuts. This is the last effort I want to do. I was thinking there would be a close lug nut that I could for example just shorten the shank length.

The other issue is the current hex size of 7/16". Anything bigger and a socket will not fit over the nut as the "spokes" will interfere. Then I would need a different type with the drive internal to the lug nut and I really don't want those types.

Thanks Tim

You're not likely to find lugs with the dimensions of your sample.
 Mamba lugs would probably be the closest shank dia. can you measure the hole in the wheel and see what diameter it is? I'm hoping it's .562 if smaller you might have to buy a set and have the shanks turned down. If the mamba style fits the hole cutting some length off would be easy enough. Or look for a shorter 9/16 shank.
Another option take the wheels to a shop that can accurately drill out the holes to 5/8" and use the common minilite lugs.

Looks like a Pos-a-traction wheel. I have bought a few sets of shank lug nuts here. You need metric measurements, these are english cars afterall. //minisport.com.au/

Hello.

I am in need of Qty 16 Wheel Lug Nuts  3/8-24 NF Prefer chrome.  These are for 10" wheels.

The problem is the hex and shank dia.  The shank dia is .500 x .500 shank length. The Hex is .430 across flats.

I also need washers with them. Washer OD=.892 x washer ID=.519 x washer thick= .125

Hope someone can help.  I have searched:
Mini Mania
Mini City
Little Britsh Car Co
Cooper S Import
Mini Sport

I posted a picture of the wheel and of the lug nut.  Maybe someone can identify the wheel, which may be of some help.  There were no markings inside or out on the wheel that I could tell.

Thanks much for any help.
